The glass capillary viscometers serve to determine the level of kinematic viscosity. They come in versions such as Ubbelohde, Micro-Ubbelohde, Micro-Ostwald, and Cannon-Fenske.

The iVisc is a fully automatic and compact viscometer with an excellent price-performance ratio for viscosity levels between 0.3 and 30,000 mm/s.

The modular setup of the automatic PVS viscometer with modern Windows software can be optimally adapted to any application. The VRM cleaning modules enable the fully automatic cleaning and drying of the glass capillary viscometers. The VAS viscosity auto-samplers offer the maximum convenience of automation with high sample throughput.The sample preparation systems with high-quality balances, dosing systems and magnetic stirrers enable the exact manufacture of polymer solutions via direct PC control.

Proline thermostats of the PV and PVL series are specially optimized for viscometry. The PV thermostats are particularly suited to high-temperature applications of up to 230 C. High-quality insulated PVL thermostats can be used in applications as low as -60 C.

Offering a good-value alternative in the temperature range up to 105 C are the viscothermostats, which come optionally with transparent baths of the ET series or stainless steel baths with insulated glass panes of the Viscotemp series. With the new Viscocool thermostat integrated Peltier elements replace cooling water and additional coolers.

With more than 50 years of experience and a unique product portfolio ranging from compact laboratory thermostats to industrial circulation chillers to customized heating and cooling system projects with more than 400 kilowatts of cooling power, LAUDA is the only company that can guarantee optimized temperature throughout the entire value-added chain for its 10,000 plus customers worldwide.

Quality products from LAUDA keep temperatures constant to an impressive 5 thousandth C or make targeted changes in an area spanning -150 to 400 C. Through active cooling or warming, pro-duction processes are accelerated or, indeed, made possible in the first place. In such cases, LAUDA, for example, replaces the uneconomical mains-water cooling with environmentally friendly and cost-efficient devices or, alternatively, uses existing forms of primary energy such as thermal discharge. LAUDA measuring in-struments determine the surface tension, tension limit and viscosity of liquids precisely.

As a highly specialized niche provider, LAUDA ranks either first or second in almost all future-oriented sectors. In the semi-conductor industry, all the renowned manufacturers and suppliers place their trust in LAUDA thermostats and heating and cooling systems. LAUDA quality products also enable both the research and mass production of vital medicines. In the growing medical technolo-gy market, circulation chillers made by LAUDA cool patients and guarantee safe open-heart surgery. LAUDA industrial circulation chillers provide reliable and cost effective cooling for printing ma-chines, injection moulding plants and laser processing machines. Further principle applications include material inspection, biotech-nology and the cooling of laboratory instruments and machines. LAUDA thermostats are, naturally, also used in the measuring in-struments manufactured by us. For example, in order to determine the viscosity of aviation fuel under real conditions at 10,000-meter altitude, the sample is cooled in the laboratory down to -60 C.

Through numerous innovations and ongoing investment, LAUDA is sustainably improving its excellent market position and is growing both in the main European market as well as overseas.

The greatest precision and longevity:LAUDA glass capillary viscometers

Glass capillary viscometers are available in various models which differ in their areas of application, levels of accuracy and operation. Made from borosilicate glass (boro 3.3), these are available now at LAUDA in versions such as Ubbelohde, Cannon-Fenske, Micro-Ostwald, and in special models. Alongside the excellent chemical resi-stance, the new viscometers distinguish themselves from the rest thanks to a very small heat expansion coeffici-ent, a very high temperature fluctuation resistance, and high mechanical strength. For highly precise, automatic measurements, the Ubbelohde version with suspended ball level is preferred, among other reasons because of its independence of the flow time from the precise sample volume.

To keep measuring times in the optimum range between approx. 60 and 600 seconds, various capillary diameters are offered for different viscosity ranges. The method, particularly with automatic LAUDA measuring technology and precise temperature control using LAUDA viscother-mostats, is unrivalled in the precision for measuring liquids with nearly Newtonian (ideal) flow behavior.

Fully automatic and compact:LAUDA TD 3 tensiometer

The ring/plate method for measuring the surface and interfacial tensions of liquids is an established method with potential: The increa-sing need for surface active additives and their confir-mation in quality checks necessitate fully-automated, user-friendly devices. As a stand-alone device, the com-pact, fully-automated ring/ plate tensiometer TD 3 with

LAUDA Command remote control provides everything needed for this, both in lab environments and for on-site application. Surface and interfacial tensions can be easily measured, precisely and repeatably calculated, displayed, printed, saved, and transferred to the computer at the touch of a button.

The LAUDA TD 3 comes in a new design and is equipped with some unique technical features. As such, LAUDAs smallest thermostat, the PTT Peltier thermostating unit, for example, can be easily incorporated into the device. Extre-mely quick and convenient, the measurement samples can be thermostated from 5 to 80 C with the minimum of space requirements.

The TD 3 serves to determine the surface/interfacial properties of organic and inorganic liquids, dispersions, and emulsions, among others, for developing surface active substances like surfactants and emulsifiers as well as for confirming the same in waste waters and bodies of water.

The right temperature worldwide and the greatest precision at LAUDA these claims also extended to its high-quality constant temperature equipment and extremely high performance hea-ting and cooling systems.

LAUDA constant temperature equipment For more than 50 years LAUDA has been designing and manufactu- ring high-quality constant temperature equipment in an operating temperature range from -90 up to 400 C. Starting with water baths through to high-performance process thermostats. For routine tasks the economically priced LAUDA Alpha heating and cooling ther-mostats are the first choice. The product line ECO and Proline thermostats enable professional and, at the same time, econo-mical temperature control. High cooling outputs and fast cooling rates are offered by the Proline Kryomats. The more powerful Integral T and Integral XT process thermostats provide a light-ning-fast temperature change with external temperature control.

Robust and economical: LAUDA viscothermostats

LAUDA is expanding its range of viscothermostats for manual and automatic viscometry. With our latest thermostats, we are closing the gap between the economical ECO ET polycarbonate transparent baths and the powerful Proline PV viscothermostats. The new Viscotemp series supplements the robust, tried-and-tested stainless steel viscothermostats with its excellent price-performance ratio. A first with the Viscocool 6 with low bath volu-me is the integrated Peltier cooling and lighting in space-saving and compact design.

LAUDA much more than measuring instruments output of up to 265 kilowatts and a working temperature range from -5 up to 25 C are used by the manufacturers of, for example, printing machines, injection moulding plants and laser processing machines. LAUDA thermostats are characterized by excellent handling, high ergonomics and intuitive operation.

LAUDA heating and cooling systems In accordance with the principle of modular engineering, LAUDA

process cooling systems, heat transfer systems and secondary circuit systems are planned and built precisely according to customers wishes: process-oriented, customized and with precision control, meeting the strictest safety standards. With a temperature range of -150 up to 400 C, LAUDA systems heat and cool

to an accuracy of one tenth of a degree Celsius. As the requirements for temperature regulation systems are constantly increasing, the modern LAUDA heating and cooling modules are flexibly extendable and modifiable. The combination of planning, production, our own test bay and a comprehensive service package makes LAUDA heating and cooling systems a valued partner around the world.

This way, external cooling is not necessary in order to maintain the often required 20 or 25 C. The integrated Peltier cooling guaran-tees an operating temperature range of up to 15 C below room temperature. Of course, all of LAUDAs viscothermostats meet the high requirements of the international standards of viscosity measurement.

s Viscocool and ViscotempViscothermostats with transparent bath and Silver and Gold control headsThe tried-and-tested ET 15 baths made from polycarbonate provide space for immersion of a maximum of three glass capillary viscometers for manual measurement using the stop watch or for up to two automatic measuring stations for iVisc or S 5 (PVS). If required, when using dilution viscometers for example, up to two magnetic stirrers can be added to the thermostat.

Specifically for applications near room temperature (15 to 30 C), the ET range was expanded upon with the inclusion of the extremely compact, electronic Viscocool 6 version which is cooled using Peltier technology. It can provide cooling without a cooling water connection or any additional devices. The similarly new round solid glass bath Viscotemp 18 is used particularly for temperatures around 100 C for operation with silicone oils and with aggressive samples. Outstanding insights in the smallest space can be achieved thanks to up to five stop watch measuring stands. Alter-natively, it can be equipped with an iVisc or PVS measuring stand and thermostating position.

Viscosity measuring with Ubbelohde, Cannon-Fenske and Micro-Ostwald capillary viscometers


Determining the viscosity number, intrinsic viscosity (mean molar mass) and other parameters of technical polymers such as PA, PET, PBT, PE, PP and PVC in accordance with EN-ISO 1628, ISO 307 for the quality control of plastics

Measuring absolute viscosities of engine oils and other lubricants in accordance with ASTM D445, viscosity index in accordance with ISO 2909 at 40 and 100 C

Glass capillary viscometers are available in various designs, which differ with respect to application area, accuracy and operation. As of now, they can be supplied by LAUDA in the Ubbelohde, Cannon-Fenske, Micro-Ostwald and special designs. For high-pre-cision, automatic measuring, the Ubbelohde version with the suspended level is preferred, among other reasons because the flow time is independent of the precise sample

volume. To keep the measuring times within the optimum range between approx. 60 and 600 s, different capillary diameters are supplied to cover the complete viscosity range. The procedure, particularly with automatic LAUDA measuring technology and precise temperature control using LAUDA clear-view thermostats, is unrivaled in terms of accuracy for measuring liquids with nearly Newtonian (ideal) flow properties.

Accurate and standard-compliant

Capillary viscometer for fully automatic viscosity measurement and evaluation


Determining viscosity numbers for quality assurance in the plastics industry

Absolute viscosities in the petroleum industry for motor oil, lubricant, fuel, kerosene, additives, etc.

Determining chain length of pharmaceutical and biological macro-molecules

The fully automatic, space-saving iVisc is easy to operate and suitable for getting started in professional viscometry. Simply insert the USB cable into the PC or netbook, start the software and the capillary viscometer is ready to go. The state-of-the-art measuring instrument offers a Windows user interface which could not have a more intuitive or easy design. As such, the sys-tem condition, the ongoing measuring or pause times as well as the measuring data in table form can be seen at a glance. The capillary

data can be transferred into the measuring win-dow via drag & drop. Using pull down menus, important application-specific evaluations and all common approximation formulas for intrin-sic viscosities (IV values) can be specified as a measure for polymer chain lengths. By taking the necessary corrections into account, the ab-solute kinematic viscosities and, if the density is known, the dynamic viscosities can be eva-luated from the precisely measured processing times.

We had the user in mind ...

The full control of the measuring process including the pumps and pressure compensation valves, the highly flexible meniscus sensing using NIR light sensor, and the precise measurement of the flow time of the sample using the measuring capillary are all done in the head of the measuring stand. Standard-compliant measurements of the K-value, intrinsic, reduced, and inherent viscosity are made possible out-of-the-box. Complex measuring applications can also be easily established and configured.

The most common formulas and calculations are included in the software. The clear software interface considerably simplifies measuring praxis. After the simple insertion of a filled glass capillary, a software program coordinates all of the steps necessary to perform the measurement and it then executes the evaluation. Here, the precise measuring of the flow time is based on intelligent, self-adaptive NIR meniscus sensing.

Step 1: Identification of the capillary type

Step 2: Selection of desired measurements

Step 3: Start

Step 4: Issue of the measurement protocol

Integrated glass viscometer database Display of the current measuring and pause times Software clearly designed for a single display window

Easy data transfer possible (e.g. Excel)

Modular processor viscosity measuring system for efficient system solutions


Production-accompanying specification of viscosity numbers for technical plastics

Measurement of the viscosity index for classification of motor oils

Determining absolute viscosities of fuels at application temperatures

Determining chain lengths of hyaluronic acid products and resorbable polymers

The modular structure of the LAUDA PVS system permits efficient system solutions which are perfectly adapted to the needs of users. This way, you can design the configu-rations very flexibly for a higher number of samples and new tasks by integrating spe-cial components and software modules. The extensive automation; for example, with the cleaning of the glass capillary viscometers, the sample preparation and sample loading, maxi-

mizes efficiency while keeping manual efforts to a minimum. The associated reduction in use and contact with chemicals makes a telling contribution to occupational safety and envi-ronmental protection. LAUDA PVS is made up of stand-alone, independent functional units. Measuring stands, cleaning modules, automa-tic samplers and dosing systems are control-led centrally from an easy to operate Windows measuring program.

PVS Viscometer basic modules The measuring stand S 5 The S 5 is the actual measuring station of the PVS system. The head of the stand-alone measuring stand S 5 is comprised of the opto-electronic meniscus detectors as well as the entire micro-processor control of the measuring process including miniature pump and valves in the head of the unit. The measuring time of the sample is determined to the millisecond using a processor-controlled infrared light sensor. The robust micro-pump for pushing the sample up into the measuring ball as well as the chemical-resistant valves in the head of the stand make reliable continuous opera-tion possible.

The control unit PVS 1The PVS 1 control unit is the core of the system as well as the switching station between the PC and individual components. It can be equipped with up to four inserts depending on the configuration.

VRMCleaning modules The cleaning modules enable the fully automatic cleaning and drying of the viscometers. Depending on the fittings, one or two viscometers can be connected and two different cleaning liquids can be selected separately. Even very hot samples of up to 160 C or highly viscous samples with 1,000 mm/s can be pumped out into waste bottles with pre-dilution. The glass viscometers can then be cleaned using cleaning solvents and dried with a volatile solvent and ambient air. High-quality materials guarantee resistance to many common solvents. With the VRM 4 S, even concentra-ted sulfuric acid can be used for cleaning.

Special features:

Automatic (online) rinsing of the viscometer Inert and corrosion-free for all standard solvents Individual specification of cleaning procedures using PC software

Automatical filling and draining Two different rinsing agents (the first for cleaning, the second for drying)

VAS Fully automatic sampler The sampler based on the Combi-PAL sampler of CTC offers the con-venience of full automation at the highest sample throughput rate as an add-on to the two-station (VAS 1/2) or four-station (VAS 1/4) measuring systems. Depending on the size of the sample bottles, up to 63 samples can be processed in one session. Heated sample racks with similarly thermostated syringes guarantee trouble-free measurement of hot poly-mer solutions or oils without the samples cooling down over the course of the process. The system is controlled using a special PVS program which permits the safe application-specific allocation of the measurement samp les to the matching glass viscometers, e.g. through direct drag & drop from the task list which was generated during sample preparation. The measurement of the samples is done in the S 5 measuring stand, whi le the cleaning of the glass capillary viscometers and dosing syringes is done via suitable VRM modules.

Special features:

Retrofittable two-station measuring system VAS 1/2 Four-station measuring system VAS 1/4 for the highest sample throughput Heatable sample rack and syringe for highly- viscous samples or temperature-critical samples Easy to program sample processing Fast sample switching possible Assignment of processing priorities Sample-specific applications can be defined (e.g. kinematic and relative viscosity, IV and K-values) Direct injection into viscometers without contami- nation at the tubing Optional rinsing with two solvents or with next sample Automatic program-controlled sample locks

Automatic sample preparation for polymer solutions These stations are based on the dosing units of Mettler-Toledo and are operated for PC-controlled solvent loading, e.g. in order to determine the limiting viscosity number (intrinsic viscosity and molecular mass) with programmable concentration levels. In this regard, special dilution visco-meters are used in viscothermostats equipped with magnetic stirrers (see from page 10).

In connection with Mettler-Toledo XP-type laboratory balances and an additional software module, the preparation of well-defined polymer- solutions can be carried out quickly and safely via PC in a stand-alone dissolving station with just a few manual operations and without the com-mon and laborious weighing process. The proper, standards-compliant solution concentration is always automatically produced according to standards while taking the filler content into account.

Special features:

Automatic dilution series can be executed on up to four measuring stations simultaneously Specially developed RS 232 interface box Multiple dosing systems can be controlled via PC or plug-in board for PVS Can also be combined with VRM Can also be used in connection with integrated magnetic stirrers for in-situ sample preparation High-quality XP balance and special software module for gravimetric or volumetric dosing No influence on the solvent temperature and pre- thermostating not necessary Direct transfer of concentration and initial weight to the PVS software User navigation via high-resolution display on the balance Input of sample data via PC or barcode reader Multiple solvents can be added for different sample types

Software based on Windows

All PVS system configurations are controlled by a standard PC through an interface. In addition, the high-performance and user-friendly standard version of the PC program calculates the kinematic, dynamic, relative, re-duced and inherent viscosity and the K-value from the measured running times. Further key material figures can be determined using additional software modules.

The user is given comprehensive support by the program. All parameters are entered on the PC via mouse-click and keyboard and transferred via the interface to the PVS system.

The measuring results and evaluations can be printed out in the form of a log and saved in a file in ASCII format. The measurements report logs all measuring data on a day in chronological order and saves them in a file marked with the days date. This data can be viewed at all times which means that consistent documentation is guaranteed. Further processing in other programs, like MS Excel for example, and in other networks can be accomplished without any problems.

Software basis:

Windows software, runs on all conventional PCs and operating systems

Parallel operation of up to eight measuring stations Calculation and display of: - Processing times and their mean values - Standard deviation - Kinetic energy correction (e.g. according to Hagenbach or ISO 1628/6) - Absolute kinematic viscosity - Absolute dynamic viscosity - Relative viscosity - Reduced viscosity (viscosity number) - Inherent viscosity (logarithmic viscosity number) - K-value according to Fickentscher

LAUDA TD


Determining the aging of insulating oils via interfacial tension

Inspection of cleaning water by determining the surface tension

Characterization of surfactants for detergents and cosmetics

The LAUDA TD tensiometers perform measurements with the Du Noy ring and Wilhelmy plate according to international standards. Thanks to the powerful load cell with significantly advanced measuring range, it is also possible to determine the densities according to the Archimedes principle as well as to measure small weights. The measuring table with sample plate can be moved smooth-ly without any jerking motions in order to, for example, place the Wilhelmy plate on the sam-

ple surface or find the maximum force during ring measurement. The tensiometers come in a new design and are equipped with some unique technical features. As such, the worlds smallest thermostat, the LAUDA PTT Peltier thermostating unit can be easily incorporated into the device. Surface and interfacial tensi-ons can be easily measured, precisely and re-peatably calculated, displayed, printed, saved and transferred to the computer with a single keystroke.

s TD 1 CRing/Plate tensiometer In the large work area which can be accessed from all sides of the instru-ment, various conventional sample beakers with diameters up to 8 cm can be used. The thermostating of the sample can, for example, be done using the LAUDA PTT Peltier thermostating unit. On the high-resolution display of the Command remote control, the wetting force increase when removing the ring can be traced and the maximum force set without breaking the lamella. The value shown as the maximum is automatically corrected according to Zuidema and Waters and thus corresponds to the surface tension of the measured liquids in mN/m. At the touch of a button, the measured value, together with all the parameters, can be temporarily saved or exported directly to an optional logging printer.

TD 3Ring/Plate tensiometer With the LAUDA TD 3, the measurement samples in the range from 5 to 80 C can be thermostated extremely quickly and conveniently with the smallest of space requirements. The tensiometer serves to determine the surface/interfacial properties of organic and inorganic liquids (liquid/liquid or liquid/gas), dispersions, and emulsions (among others, for developing surface active substances like surfactants and emulsifiers) as well as for confirming their presence in waste water and other water samples. The integrated micro-controller takes care of the table positioning, maximum recognition and measurement data correction for the user. The program repeats measurements until such a time as the measurement value stability as set by the user has been reached and then calculates the static surface or interfacial tension. The measurements can be executed completely in-dependently of the user and are more precise than the most important standards demand. As such, the equipment satisfies all of the requirements of the stringent GLP guidelines. In addition, both liquid density and low weights can be easily determined.

Special features:

Automatic maximum detection and maximum scanning Output of the measured values to optional printer or data transfer to PC via RS 232C Automatic measurement value corrections according to Zuidema and Waters Statistical check of the measurement value stability Storage of up to 500 measurement results with parameters Numeric, user-defined sample designation Granite base plate for vibration absorption and increasing stability Background lighting of the measuring chamber Waiting period prior to start of measurement can be programmed (ASTM D971)
